Negative Effects of Coal Mining TheWorldCounts

Chemical, Air & Dust Pollution: Underground mining allows coal companies to dig for coal deeper into the ground. The problem is that huge amounts of earth and rock are brought up from the bowels of the earth. These mining wastes can become toxic when they are exposed to air and water. Examples of toxins are mercury, arsenic, fluorine and selenium.
